it It whom it 17mg concern:

Be it known that I, Trioinis It. MORGAN, Sr., of Alliance, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Clutches, and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art ,to which it appertains to make and use the same.

My invention relates to an improvement in clutches, the object being to provide a friction-clutch of such construction that bevel r clutches, so that by shifting a single key one clutch is locked and the other unlocked, or both may be disconnected from theshaft.

With these ends in view myinvention consists in certain features of construction and combination of parts, as will hereinafterbc described; and pointed out in the claims; l

In the accompanying drawings, Figure 1 is a View, partly in side elevation and partly in longitudinal section, 'of a clutch embodying my invention. Fig. 2 is a side elevation of the double key. Fig. 8 is an end view of one of the clutches. Fig. at is a view, partly in end elevation and partly in transverse section, of the shifting collar and lever of the clutch. Figs. 5, 6, and 7 represent a modification.

' A represents a shaft, from which itis desired to transmit motion in opposite directions to another shaft. A longitudinal groove, A, is formed in the shaft A, in which is placed the sliding key A ,which latter is constructed with the central projection, a, and the end projections, a a, as clearly illustrated in Fig. 2.

is a collar or sleeve loosely secured on the shaft, and provided with a recess,in which is received the central projection, a, of the sliding'key, whereby the latter is moved in either direction by sliding the collar or sleeve back and forth on the shaft.

A is a shifting-lever j ournaled ona post or stud, A", and constructed with a forked end, in the arms a a of which are secured the pins or studs a on which are-mounted the antiengaging in the correspondingly-formed recessesin said collars. Thus, by operating the shifting-lever A the sliding key is moved in either direction, carrying with it the conical collars or sleeves B B.

To the shaft A is rigidly secured the cross bar 0 of each clutch, by a sleeve, 0, that is firmly attached to the shaft, thereby causing them to rotate therewith. Each cross-bar O has connected therewith. a yielding face-plate, D, by means of screws D, that extend through openings (1 in the face-plate and into screwthreaded sockets din the cross-bars. Spiral springs d encircle the outer and projecting ends of the screws, the outer ends of said springs restingagainst the heads of the screws, while the opposite ends bear against the faceplate, thus serving to force the latter in a yielding manner against the cross-bar C. Curved leversfE E are pivoted at 0 etc the cross-bars, the long curved arms E of the levers being arranged to engage the conical surface of the collar B, while the short arm FF engages the sleeve or projection E on the face-plate D.

Bevel-wheel F is loosely mounted on the shaft A, and is provided with a sleeve, F, on which is placed the clutch-disk G, which is secured by means of the screws G entering screwthreaded openings formed in the rear face of the bevel-wheel. Clutch-disk G is provided with an annular groove,which is undercut and formed with converging walls h 71 Within the annular grooves h are placed the triangular-shaped blocks J, having recesses in their converging faces, in which are removably secured the wearing-surfaces K. Through openings in the crossbar G and face-plate D are inserted the bolts L, having secured to their inner ends the blocks G, and to their outer ends the lock-nuts N. When the shifting collar or sleeve A is moved toward the right,the

conical collar or sleeve B will engage thelong arms E of the levers E, forcing said arms outwardly, the effect of which is to force the clutch-disk G toward the cross-bar C, and thereby cause the friction blocks or plates K,- attached to the inner face of the crossbar O,

to engage the adjacent face of the disk G and,

form a lockingsurface therewith. At the same time the levers E also operate to draw the bolts L outwardly and cause the frictionsurfaces on the friction-blocks J to engage and become locked to the converging walls of the annular groove in the clutch-disk G. Thus it will be observed that the clutch-disk, which is attached to the bevel-pinion, is firmly locked to the cross-bar of the clutch by the frictional locking-surface between the clutch-disk and the cross-bar and the locking-surfaces within the annular groove.- When the clutch is op-- erated in the manner described, the other clutch is operated simultaneously therewith, but in an opposite direction, so as to release the bevel-wheel from the shaft A. hen the grooved or shifting collar A is moved in the opposite direction, the long arms E of the clutch-levers are allowed to approach each other,and thereby permit the spiral spring referred to to draw the face-plate .D toward the cross-bar O and release both sets of friction surfaces or plates from contact with the disk G. Thus it will be observed that the bevel-wheels may be readily and firmly locked to the clutch to revolve therewith; that upon locking one bevel-wheel to the clutch the other wheel is simultaneously disconnected from its clutch, while by adjusting the shifting collar A equidistant from the two bevel-wheels the latter are both disengaged from their clutches.

One important feature of the invention consists in the construction of parts whereby the frictional locking-surfaces are not dependent on the area or size or form of the bevel-whee1s. If it is desired, bevel-wheels of small diameter may be employed, and yet a powerful lockingaction of the clutch insured by the employment of a clutch-disk and its accompanying devices of sufficient diameter and area to insure an extended frictional locking-surface. The bevel-wheels mesh into a bevel-wheel located between them and at right angles thereto; and hence, when one of the bevel-wheels of the clutch is locked to the shaft to rotate therewith said driven bevel-wheel will be rotated in one direction, and will be rotated in the opposite direction by locking the other bevelwheel of the clutch to the shaft.

with the gear-wheel I.

In this modified construction of parts the shiftingcollar or sleeve Q is provided with conical surfaces on its opposite ends for operating the clutch-levers.

It is evident that many changes may be made in the construction and arrangement of parts ver for simultaneously locking one clutch and releasing the other, substantially as set forth.

2. The combination, with two clutches hav-. ing bevel or gear Wheels or pinions connected therewith, of a shifting collar or sleeve and a,

sliding key for simultaneously locking and unlocking said clutches, substantially as and for the purpose set forth.

3. The combination, with a pinion, bevel, or g'ear wheel loosely mounted on a shaft, and a clutch-disk secured thereto, of accross-bar keyed to the shaft, a face-plate secured in a yielding manner to said cross-bar, and a sliding collar and levers for operating said faceplate, substantially as and for the purpose set forth.

4. The combination, with a bevel-whee gear-wheel, or pinion loosely mounted on a shaft and having a clutch-disk secured thereto, the latter being provided with an annular groove, of a cross-bar keyed to said shaft, a face-plate secured to the cross-bar in a yielding manner, and bolts extending through the face-plate and cross-bar, and provided with friction-blocks that engage in the annular groove in the clutch-disk, substantially as and for the purpose set forth.

5. The combination, with the bevel-wheel F, clutch-disk G, provided with the annular groove H, of the cross-bar O, faceplate D, bolts L, levers E, conical blocks B, and the frictionsurfaces K N, substantially as and for the pur- THOMAS n. MORGAN, s 1.
